Grow room setup

i have a closet thats 4'x5' and im looking for some advise on a ideal set up that would be sure to work, im looking for advice mainly on best lighting for up to say 12 plants in this 4x5 space for veg and flowering stages can someone plz help with some advice

I'd go with a 1000 watt hps in that space. Just make sure you can properly vent the closet to keep your temps in check.

1000w would be nice, if you are not ready to make the plunge to 1k go with a 400w switchable that you could always use for veg when you step it up. a 600w would be real nice too but same cost as a 1000w. go for the 1k
